使用场景
Usage Scenarios
表达普遍观点
在学术写作中，表达观点时应避免过度主观的 I think 或 I believe。更推荐使用客观句型，如 It is widely argued that、It is generally accepted that 或 There is growing evidence that。这类结构适合用于引言段或主体段开头。
It is generally accepted that access to quality education can enhance social mobility.
人们普遍认为，获得高质量教育可以促进社会流动。
There is growing evidence that regular physical activity improves mental health.
越来越多的证据表明，规律的体育活动有助于改善心理健康。
解释原因与结果
PTE 和 IELTS 写作经常要求考生解释问题产生的原因及其影响。常用结构包括 lead to、result in、contribute to、be associated with 和 have a significant impact on。使用这些结构时要注意主谓搭配和介词准确性。
Rapid urbanisation has led to increased pressure on public transport systems.
快速城市化给公共交通系统带来了更大的压力。
A lack of financial support may result in lower completion rates among university students.
缺乏经济支持可能导致大学生完成学业的比例下降。
进行对比与让步
学术写作需要展示平衡分析能力。对比结构如 whereas、while、in contrast 和 on the other hand 可用于比较不同观点；让步结构如 although、despite 和 even though 可用于承认反方观点后提出自己的分析。
While online learning offers greater flexibility, face-to-face instruction provides more direct interaction.
虽然在线学习提供了更大的灵活性，但面对面教学能提供更直接的互动。
Despite its high initial cost, renewable energy can be economically beneficial in the long term.
尽管初始成本较高，可再生能源从长远来看可能具有经济效益。
引入证据或研究发现
在 IELTS Task 2 和 PTE Write Essay 中，考生不一定需要引用真实数据，但可以使用学术化表达引入一般性证据。常见句型包括 Research suggests that、Studies indicate that 和 Evidence shows that。
Research suggests that early childhood education has long-term benefits for cognitive development.
研究表明，幼儿教育对认知发展具有长期益处。
Evidence shows that excessive screen time can negatively affect children's attention spans.
证据显示，过度使用电子屏幕可能对儿童的注意力持续时间产生负面影响。
提出评价与结论
结论段和主体段分析句需要清晰评价某种现象的重要性、可行性或影响。常用表达包括 it is essential to、it is necessary for、is likely to 和 plays a vital role in。
It is essential to implement policies that encourage sustainable consumption.
实施鼓励可持续消费的政策是非常必要的。
Government intervention is likely to play a vital role in addressing housing affordability.

常见错误
Common Mistakes
Incorrect
❌ People are agree that education is important.
Correct
✅ People agree that education is important. / It is widely agreed that education is important.
agree 是动词，不能写成 are agree。中国学习者常受中文“是同意的”影响而误加 be 动词。若要使用更学术的表达，可改为被动结构 It is widely agreed that。
Incorrect
❌ Although technology is useful, but it has some disadvantages.
Correct
✅ Although technology is useful, it has some disadvantages.
although 和 but 不能在同一个从句结构中同时使用。中文可以说“虽然……但是……”，但英文中 although 已经表达让步关系，因此主句前不再加 but。
Incorrect
❌ The government should take actions to solve this problem.
Correct
✅ The government should take action to address this problem.
take action 是固定搭配，action 在此通常作不可数名词。solve this problem 可以使用，但在学术写作中 address this problem 更正式，表示“处理、应对问题”。
Incorrect
❌ This phenomenon brings many negative influences.
Correct
✅ This phenomenon has many negative effects. / This phenomenon may have a negative impact on society.
中文“带来负面影响”不能直接翻译为 bring negative influences。英语中更自然的搭配是 have negative effects 或 have a negative impact on。
Incorrect
❌ With the development of society, people pay more attention to health.
Correct
✅ As society develops, people are paying greater attention to health.
With the development of society 虽然语法上可行，但在中国考生作文中过度使用，显得模板化。更自然的学术表达可以使用 As society develops 或 In recent decades。
Incorrect
❌ It is no doubt that climate change is serious.
Correct
✅ There is no doubt that climate change is a serious issue.
正确结构是 There is no doubt that，而不是 It is no doubt that。另外，serious 后接名词 issue 可使表达更完整、更学术。
Incorrect
❌ The reason is because many people lack awareness.
Correct
✅ The reason is that many people lack awareness. / This is because many people lack awareness.
The reason is because 属于常见冗余错误。reason 后通常接 that 从句；如果使用 because，则可写 This is because。
Incorrect
❌ More and more people use private cars, which causes air pollution becomes worse.
Correct
✅ The increasing use of private cars has worsened air pollution. / More people are using private cars, which has worsened air pollution.
which causes 后不能直接接完整句 air pollution becomes worse。可以使用 cause + noun + to do，或改为 which has worsened air pollution。

Academic Sentence Patterns 在 PTE Academic 中使用频率很高，尤其影响 Written Discourse、Grammar、Vocabulary 和 Content 的表现。在 Write Essay 中，考生需要用清晰的主题句、原因句、例证句和总结句组织观点；在 Summarize Written Text 中，需要将多个信息点压缩为一个语法正确、逻辑清晰的长句；在 Summarize Spoken Text 中，学术句型有助于准确概括讲座内容并表达因果关系。高分答案通常不是使用过度复杂的句子，而是使用结构稳定、连接自然、表达客观的学术句型。

AI 学习建议
AI Learning Tips
在 PTE Write Essay 中，每个主体段建议至少包含一个清晰的 topic sentence，例如 This issue can be explained from both economic and social perspectives.
避免将中文句子逐词翻译成英文。学术英语更重视动词搭配，例如“产生影响”应写成 have an impact on，而不是 bring influence.
不要为了追求复杂而滥用被动语态。被动语态适合强调行为或结果，如 Measures should be implemented，但表达观点时主动语态通常更清晰。
写 IELTS Task 2 时，可以用让步句展示平衡分析，例如 Although this approach has limitations, it remains practical in many contexts.
Summarize Written Text 中应使用一个主句承载核心意思，并用 which、while、because 或 although 连接次要信息，避免写成多个独立句。
